mainnet and sepolia gas_used for transmissions is ~117600 500k is more than enough and in line w/ others BumpPercent dominates BumpMin - stays at default

Following the Mantle Arsia upgrade,
eth_estimateGasnow returns pure L2 execution gas (no amortised L1 data costs anymore). Our transactions use about ~117,600. After INCIDENT-2427 NOPs overrodeLimitDefaultto500_000.Still a ~4× overestimate but nothing that would cause issues, and is in line with other EVMs so for consistency that's what we're picking here.
BumpPercent(20) dominates overBumpMin- no point in changing it.BumpPercentchain-override for testnet.LimitMaxisn't used inBlockHistoryEstimator- its presence is misleading, so removed.Requires
